I found a 10" Columbiad with an eye bolt blacksmith welded in the fuse hole, it took a lot of doing but I got it out and inside was a 2" wood screw, a blue trade bead, a brass bullet casing, 2 iron brads, an oyster shell, a 4 1/2" piece of wood, 2 horse shoe nails, 2 short iron rods, and 9 miscellaneous iron scraps, it looked like they swept off the workbench and put the trash in the shell, pretty interesting to me. I also remember hearing about the fuse Dr South found at Ft Fisher
